Lenovo laptop blues, memory issues

Question re my lenovo laptop, os windows 7, spyhunter, Bitdefender installed, laptop clean, no virus. Laptop fine in safe mode,61% memory used safe mode, with 718MB avail. I can only use this laptop now in safemode, as when I open in normal mode, within 4 minutes a large no of exe files open, almost twice as many as in safe mode. Then the screen freezes up. any suggestions please. I have stopped as many exes as I can. I do not have this issue on my other lenovo laptop which has similar applications installed. btw, both laptops have RAM of 2. Plenty of memory free on hard drive.
